Anyone with stretched Falken ZE522's?

[PoLonY]

Guys, did a search, found nothing on these particular tyres here. Busy looking for a replacement tyre for my 2 front Pirellis and was given a great price on the Falken 522 series in 205/40R17. Will be stretched on a 9J. I wondered if anyone had experience stretching this particular model, wonder if the stretch anything like the 512's?

Wanna fit these asap but need to make sure they stretch well else Ill have fitment issues, so any help greatly appreciated.
